At present, compressed air is required to be used in the construction process of nuclear power stations at home and abroad to provide power for pneumatic tools. At present, two high-power air compressors (rated power is about 150 KW) are generally adopted to directly provide compressed air for two units in a nuclear power site. However, the nuclear power site has the advantages of large occupied area, large construction work amount and long construction period, and personnel can be arranged to carry out overtime work at noon and night in order to ensure the construction progress of the site. As the nuclear power construction is 24h shift construction in the peak period, the compressed air on the site can be supplied for 24 h. However, compressed air is not used on site at all times, and the large-scale air compressor is operated at the peak time of air consumption and at the low peak time of air consumption, so that the air compressor is ineffective and has more work.
